Abstract

Thermoelectric generators(TEG) is considered as a promising technology for utilizing low-grade thermal energy, while the cooling system plays a key role in TEG. A two-dimensional numerical model of jet impinging jet cooling is developed based on the commercial code FLUENT. The influences of several factors on thermoelectric conversion efficiency are observed. The factors include the air inlet velocity, the TE legs height, and the fins. The results show that the air inlet velocity is one of the most important factors for the cooling performance, the convection heat transfer efficiency and conversion efficiency significantly increases with the improvement of the air velocity. Higher TE legs height can influence the TEG performance effectively, 5~7mm legs height is recommended in this study. And fins can effectively increase the TEG efficiency, the thermoelectric conversion efficiency with 1mm×1mm fins is 6.73% which was 2.4 times higher than without fins.
